By Prof. Asif Qureshi | IIT Hyderabad

Learners enrolled: 4253 | Exam registration: 1388

ABOUT THE COURSE:
Air pollution is a very serious problem. While most courses target outdoor air pollution, this course will focus on Indoor Air Pollution, a very important current topic. Course will cover the types of indoor air pollutants, sources of these pollutants, their effects, measures for control, and indoor air quality modeling.

INTENDED AUDIENCE:

Students (PG and senior UG).
Working professionals in field of environmental engineering and air pollution, and its control.
Junior scientists and engineers of pollution control boards.
Non-engineering background executives of private industries dealing with air pollution and its control.
Non-engineering background executives from governmental agencies such as pollution control boards and other state/national bodies, those who are dealing with or are interested in air pollution and its control.
Senior level scientists
Regulators and policy makers from ministry and other professional and governmental bodies.

PREREQUISITES: Basic physics, chemistry, mathematics (class 10 to 12 level)

INDUSTRY SUPPORT: Public sector power units
Iron & Steel, and other manufacturing industries
Mining sector

Week 1: Indoor air pollutants, sources and causes: Homes / Residential Environment (cooking, cleaning, occupancy, etc.); offices and schools, other commercial establishments such as saloons, fitness centers and restaurants.

Week 2: Constructing and solving of simple mass balance models of indoor air pollution. Understanding fate using concepts of half-lives and persistence/residence times.

Week 3: Outdoor air as source to indoor air: physical and chemical processes, inflow of gas and particles, exfiltration, ventilation and ventilation systems. Mechanisms of the infiltration of outdoor pollutants.

Week 4: Aerosols in the indoor atmosphere, chemical and physical properties of indoor aerosols (e.g., aerosol formation, coagulation, deposition, gas-particle partitioning).

Week 5: Chemical kinetics: collision theory, rates of reactions. Important chemical reactions in indoor air. Difference from indoor air. Reactions on surfaces.

Week 6: Bioaerosol/Biological particles in indoor atmosphere. Properties and sinks. Environmental factors controlling bioaerosol concentrations (e.g., relative humidity, temperature, ventilation, occupancy).

Week 7: Indoor and outdoor air as contributor to human exposure. Method/Models for human exposure (e.g. using time-activity information) and risk assessment.

Week 8: Indoor air pollution monitoring (physic-chemical): sampling and analysis methods, and instrumentations.

Week 9: Indoor air pollution monitoring (biological): sampling and analysis methods, and instrumentations. Guest Lecture.

Week 10: Indoor air pollution/quality in the Indian context. Information on indoor air pollution. Guest Lecture. Overview and gaps.

Week 11: Indoor air quality guidelines and standards for controlling factors (e.g. ventilation, temperature) as per various agencies such as WHO, OSHA, EPA. Introduction to CONTAM, a free software on indoor air quality and ventilation analysis.

Week 12: Indoor air pollution control methods. Effects of indoor air pollution; Sick building Syndrome; Example design using CONTAM.
